DESCRIPTION 

10/20/2020 10/27/2020 New document to determine the effect of issuing 

revisions to ORAUT-TKBS-0029 (Pinellas Plant 

TBD) on previously completed claims. 

Incorporate NIOSH comments. 

1.0 Description 

ORAUT-TKBS-0029, the Pinellas Plant Site Profile consists of six Technical Basis 

Documents (TBD) pertaining to different parts of reconstructing radiation dose at the 

plant. Previous revisions to these parts were reviewed under PER-0028. Since that time, 

several reviews have been conducted resulting in revisions to ORAUT-TKBS-0029-6, 

Pinellas Plant Occupational External Dose. The last approved revision was issued on 

12/11/2017. The effect of issuing revisions to the TBD on previously completed claims 

is the subject of this PER. 

2.0 Issue Evaluation 

Revisions to the Pinellas Plant TBD include: 

- Eliminating the assignment of onsite ambient external dose and replacing it with 

the more favorable unmonitored dose. 

- Monitored and unmonitored tritium doses increased for all years.

These changes mean all previously completed claims are affected and none can be 

eliminated from further evaluation based on the changes. Additional changes did occur, 

but it is unnecessary to itemize them here since all claims must be evaluated. 

3.0 Plan for Resolving Corrective Action 

A search of the NIOSH OCAS Claims Tracking System (NOCTS) database plus a text 

search of dose reconstruction reports created an initial population of 529 claims. Of 

these, 16 had been pulled by the Department of Labor (DOL) from dose reconstruction 

for various reasons including being compensable under a Special Exposure Cohort (SEC) 

class. An additional 7 claims were active at NIOSH after being returned for various 

reasons. Those would get a new dose reconstruction based on the revised TBD so 

evaluation under this PER is not necessary. 

Seventy-six claims were eliminated because the previous probability of causation (POC) 

was greater than 50%. Four claims met the criteria for compensation under an SEC (for a 

site other than Pinellas) and no longer needed a dose reconstruction while 39 claims had 

no Pinellas employment or visits. The dose reconstruction report for those had 

mentioned the Pinellas plant for other reasons. 

Finally, 3 claims were eliminated from further evaluation because they had been 

completed after the TBD was revised. This results in 384 claims requiring further 

evaluation under this PER. Prior to this evaluation, 4 additional claims were returned to 

NIOSH for a revised dose reconstruction. Those 4 will be revised based on the revised 

TBD and so they were removed from further evaluation under this PER. 

Doses for these 380 remaining claims were recalculated using the site profile as well as 

all other applicable procedures. The POC for 379 claims resulted in a new POC below 

45%. The POC fell between 45% and 50% for 1 claim. For that claim, IREP was run 30 

times with 10,000 iterations for each run in accordance with NIOSH procedures. As a 

result, the claim remained below 50%. No claims resulted in a POC greater than 50%. 

NIOSH will provide the Department of Labor with the list of all the claims evaluated 

under this PER.
